This program draws a box and a few line segments, and generates a
38
radial blur outward from it. This creates flowing field effects.

This is done by rendering the scene into a small texture, then
41
repeatedly rendering increasingly-enlarged and increasingly-transparent
42
versions of that texture onto the frame buffer. As such, it's quite
43
graphics intensive: don't bother trying to run this if you don't have
44
hardware-accelerated OpenGL texture support. It will hurt your machine bad.
